Does anyone know if filesystems created under 3.2 Unix are mountable
on ver 4 filesystems? Are they basically the same? Thanks much in
advance.

>Does anyone know if filesystems created under 3.2 Unix are mountable >on ver 4 filesystems? Err, *which* 3.2 and 4? I shall assume you mean "System V Release 3.2" and "System V Release 4". Yes, both the V7-based S5 file system used in 3.2 and earlier S5 releases, and the 4.3BSD-based UFS file system, are present in S5R4. You would mount the file systems created under 3.2 as S5 file systems, rather than UFS file systems. >Are they basically the same? Symlinks were added to the S5 file system in S5R4; other than that, the on-disk structures should basically be the same (although the implementations are fairly different in some ways). The UFS file system's on-disk structures are, of course, quite different from the S5 file system's.

Thanks much in > advance. If you mean "will a file system created on SVR3.2 still be mountable on SVR4.0?", the answer is, in general, yes. It depends on the exact type of the file system, but the stock System V file system format didn't change. Steve Rago sar@attunix.att.com
